Hi,Can anyone recommend a suitable graphic card. It must be capable of 10bit/ch (or greater) colour depth. I am NOT using it for gaming but for graphics work and my monitor is 10bit/ch and presumably not being driven to its full potential. AMD, Nvidia or ATI (is this not AMD now?) I currently use a 6 core AMD processor with 8Gb RAM and run Debian Wheezy.Thank you in advance for your help.John

It would depend on whether you use the propitiatory drivers or the open-source ones but I have found that nVidia's drivers to be less buggy than AMD's ATM that may change in the future but for your use I would recommend nVidia and if you use blender you get CUDA support for rendering.
